TOLERANCE AND TYPE NUMBER DESIGNATION
The type numbers listed indicate a tolerance of
5%.
3.
ZENER VOLTAGE (V
Z
) MEASUREMENT
Nominal Zener voltage is measured with the device junction in thermal equilibrium with ambient temperature at 25C.
4.
ZENER IMPEDANCE (Z
Z
) DERIVATION
Z
ZT
and Z
ZK
are measured by dividing the ac voltage drop across the device by the ac current
applied. The specified limits are for I
Z(ac)
= 0.1 I
Z(dc)
with the ac frequency = 60 Hz.
